Hiya Rickers.
All fair points and we're all entitled to our own view of things.
I drew some inspiration from Nissans' anniversary badges (10 years of S and 50 years of Nissan (see attached images) and gold is obvious for 50 years.
Next, the badge is only 80mm in diameter and for it to be seen under a shaded grill (from the bonnet/hood), it needs to have clear and distinct colours. A white background was therefore ideal and in any case, 80mm all round is bigger then, for example, your idea.
After that, keep the colours simple, not only because more colours cost more money and where mine has 2x (black and gold), yours (for ex) has double that but more colours on an already small image, at distance and shaded losed its' impact.
Also, I figured that the word 'DATSUN' would speak for itself irrespective as to whether or not I used period colours schemes...ask yourself, if you removed the 'Z', would you look at your image and think Datsun Z / 240Z ? It could be almost anything and not specifically automobile related.
I'm not having a go at you and there are perhaps other designs which might have worked too ; I'm trying simply to emphasise that I thought it through and I figured that the most cost-effective* and 'punchy' image that clearly got the message across was that which I've presented here.
*After paying the molds, manufacture, shipping and then covering the cost of shipping it out to you (envelope+postage) and a free sticker (which cost to make etc), there really isn't a great margin and what I make I shall be contributing to our national clubs' first really big indoor classic-car salon next November to celebrate the Zs' 50 years....so all for a good cause !
My aim is to make some serious noise worldwide so that after 50 years hard work, the Z is truly and ubiquitously treated with all the respect it deserves as a true classic car with a full and varied competition pedigree !
